"In a recent posting (3/16/15) Jim Hamm gave us a lot of useful information on using VPNs," says Jim Hays. You'll remember VPN is Virtual Private Networking.
He goes on to say, "Intrigued, I decided to set one up, both to protect my privacy when using public wireless networks and to allow me to access my email accounts in the Prescott Library using an email client (as opposed to a web-based client). Since I will be using the VPN only while traveling or while using public hotspots I opted for Private Tunnel (https://www.privatetunnel.com/) a metered Virtual Private Networking service that provides an extremely easy to use and hassle-free experience.
"Pricing: the first 100 megabytes is free; 50 gigabytes costs $12.00; 100 gigabytes costs $20.00; 500 gigabytes costs $50.00. There is no usage time limit for the bandwidth you purchase. Private Tunnel offers clients for Mac OS, Windows, Linux, iOS and Android.
Jim concludes with, "However you can use any OpenVPN client that will run on your setup. (I used Tunnelblick (http://code.google.com/p/tunnelblick/) on my MacBook.)"
